HELP! Newbie with Errors.

So I tried to install the new version of WordPress. And just like any other idiot, I didn’t make a back-up of my files. I thought it would be simple… right….

So I tried to follow instructions and now I am seeing this whenever I go to my website

Warning: main(/home/content/j/e/n/jennifer2006/html/wp-includes/compat.php): failed to open stream: No such file or directory in /home/content/j/e/n/jennifer2006/html/wp-settings.php on line 202

Warning: main(/home/content/j/e/n/jennifer2006/html/wp-includes/compat.php): failed to open stream: No such file or directory in /home/content/j/e/n/jennifer2006/html/wp-settings.php on line 202

Fatal error: main(): Failed opening required ‘/home/content/j/e/n/jennifer2006/html/wp-includes/compat.php’ (include_path=’.:/usr/local/lib/php’) in /home/content/j/e/n/jennifer2006/html/wp-settings.php on line 202

PLEASE HELP ME! I had two years of photography business blogging, I’m wondering if I lost it all!
